Patented Nov. 18, 1930 UNITED `STATES PATENT. OFFICE ERNEST DAVIS, FSYRACUSE, NEW YORK, ASSIGNOR TO THE PROSPERITY COMPANY INC., 0FSYRACUSE, NEW YORK, .A CORPORATION 0F NEW 'YORK vPRElSSllll'G ELEMENTFOB PRESSING MACHINES Application filed January 18, 1929. Serial No.333,444.

This invention has for its object, a particularly simpleand economicalbuilt up as distinguished from a block or cast construction of thepressing element of a garment and laundry pressing machine as the heador the buck or both, by which the element is formed largely of sheetmetal stampings.

The invention consists in the novel features and in the combinations andconstructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanyingdrawing, in which like characters designate corresponding parts in allthe views.

Figure 1 is a plan view, partly broken away, of a pressing elementembodying my,

invention.

Figure 2 is a central longitudinal sectional view taken of Figure 1.

Figure 3 is a transverse sectional view of parts seen in Figure 1. f

Figure 4 is an enlarged fragmentary transverse sectional view.

This pressing machine element comprises a substantially rigid base ormain plate hav ing a pressing face, sheet metal plates overlying theman1 plate and forming a heating chamber and a conduit mounted on themain plate and extending lengthwise thereof and communicating withperforations in the main plate which open through the pressing face, theconduit being secured to the main plate and also serving to secure partsof the sheet metal plates in position.

1 designates the main plate which may be of rigid sheet metal or acasting, hut is preferably, sheet metal. y The plate 1 is formed with aline of vperforations 2 extending along the median line thereof andopening through the pressing face 3 of the plate 1.

4.- is a plate of light sheet metal having its outer margins secured asby screws 5to the plate 1 and intermediate portions oiiset to form aheating chamber 6, that is, a chamber for a heating medium as steam. The

overlies the upper face of the main plate 1 and the corrugated plate 4overlies the plate 8. The plates are secured where they touch with eachother `and to the plate 1 in any suitable manner as by spot welding.

9 is aconduitsecured to the plate 1 and communlcating with theperforations 2, this conduit being in the form of a half round channelclosed at its ends and arranged with its open side toward the plate l.It is preferably mounted over alined slots formed in the plates 4f and 8and the margins 10 of the plate 4 around the slot and also the marginsof the plate 8 around its slot extend under the edges of the channel,and means is provided for clam ing the channel toward the plate 1 andagainst said margins.

This means as here shown comprises, studs 15 threading into the plate 1and extending through the channel 9 and having heads 16 countersunk inthe upper side of the channel. Preferably, the plate is provided with.bosses 17 in which the screws or studs thread. 'lhe channel is providedalso with a block portion 18 intermediate of its ends and formed with aninlet-19 for a fluid as steam. The channel 9 is thus located between twocorrugations of the plate 4 and the space between the conduit and thewalls of the corrugation is preferably covered by' a plate Q0 secured tothe crowns of the corrugations in any suitable manner as by spot Weldingand the space around the conduit is preferably filled with a heatconducting medium as copper wool 21.

The block 18 extends through a' complemental opening in the plate 20.Preferably,

the plate 4 is enclosed in a suitable sheet 22 of heat 4insulatingmaterial as asbestos and this is covered b a cover plate 2 3 having itsmargins over ying the margins of the plate 4 and secured in position bythe screws 5. Theplate 4 is also formed with suitable offset portions 24and25 to which inlet and outlet pipes for the steam may be cou led. Thecover plate 23 is also shaped to con orm to these in ets and outlets 24,25.

26 is a. carrier by means of which the -element is secured to a supportas the yoke lever of a pressing machine, this carrier being connected tothe plate 1 by studs 27 projccting from the plate 1 between two of thecorrugations of the plate 4 and through the asbestos plate 22 and thecover plate 23. The

studs are slidably mounted in holes in the plate 26 and have heads 28.Springs 29 encircle the studs and are interposed between the carrier 26and the plate 1. Preferably, steam is projected throu h the conduit 9and the perforations 2 ang the steam is supplied from the chamber 4through a valve casing 30 mounted on the block 18 and communicating withthe inlet 19 and a conduit 31 connecting the valve casing 30 and thechamber 4. v,

The movable member of the valve in the casing 30 is operated-by asuitable handle 32 having an arm 33 coacting with the stem 34 of thevalve. Obviously, operation of the handle 32 to open the valve, willpermit the steam; to liow from the chamber 6 through the valve casing30, inlet 19` into the conduit and from the conduit out through theperforations 2.

This pressing element is particularly simple and economical inconstruction and the weight thereof carried by the rigid plate 1 andhence, the sheet metal parts other than the plate 1 relieved ofthesupporting strain and further, in that the conduit 9 for supplyingsteam is assembled in the sheet metal structure in an especially simple,eiicient and economical manner and assists in giving rigidity to thestructure and in relieving the sheet metal plates other than the plate 1of supporting stresses. l

What I claim is:

1. A'platen pressingelement forpressing machines comprising a pressingplate having perforations therethrough and opening through its pressingface, a conduit for a fluid to be projected through the perforations,the

conduit being mounted'on the plate and communicating with saidperforations and means l extending transversely through the conduit andinto the plate.

2. A platen pressing element for pressing machines comprising a pressingplate having perforations therethrough and opening through its pressingface, a conduit in the form of a channel closed at its ends and openplate to secure the conduit to the form of a channel closed at its endsand mounted on the plate over the perforations with its open side towardthe plate, whereby the channel communicates with the perforations andmeans for securing the channel to the plate, said'means comprising studsprojecting from the plate and'extending through the channel.

4. A platen pressing machine element for pressing machines comprising apressing plate having perforations therethrough opening through itspressing face, a conduit for a fluid to be projected through theopenings, the conduit being mounted on the plate and communicating withthe perforations, a sheet metal plate mounted on the pressing plate andsecured thereto and arranged to form a chamber for a heatin medium andmeans for securing the conduit to the pressf ing plate.

5. A platen pressing machine element for pressing machines comprising apressing plate having perforations therethrough o enmg through itspressin face, a conduit or a fluid to be rejected through the openings,the conduitlbeing mounted on the plate and communicating with theperforations, a sheet metal plate mounted on the pressing plate v andsecured thereto and arranged to form a chamber for a heating medium, marins of the sheet metal plate extendin un er the edges of the conduit andmeans or clampin the conduit to the rigid late against sai margins ofthe sheet metal) plate. i
